Baby Soda Bottle Science

One of the best parts of attending the Annual NAEYC Conference is the opportunity to spend time in the exhibit hall visiting all of the best early childhood vendors and getting a sneak peek at the best new toys, resources and books.

We visited a lot of vendors, and the winner of "Coolest Preschool" science experiments goes to Steve Spangler.

Of course we purchased a few pieces of science equipment for our classroom.  The first is a set of "Baby Soda Bottles."  These little test tubes are actually preformed plastic soda bottles that are sent from the manufacturer to the soft drink companies to save space.  They are extremely durable, and the soda lids fit tightly.  The bottom of the test tube looks just like the bottom of a soda bottle.  How cool is that?

During lunch bunch, we experimented with our new baby soda bottles.  First, the kiddos dropped in a little fizzy color tablet.  We bought some from the conference, but you could also use the tablets that are readily available near the baby bath supplies at the store.

Then, they filled the tubes half-way with vegetable oil.  Finally, they added warm water until it was full.  Just watching the water and oil interact is fascinating.  But when the warm water meets the color tablet, that's when the magic happens!

The students could not take their eyes off of the bottles!  What a beautiful little calm down jar disguised as a science experiment!

The bubbles and fizzing lasted for quite a while.  When the tablet was completely dissolved, then the kiddos took their time shaking the bottles and trying to mix the oil and colored water.

Stunning!  You could do this experiment with your own kiddos with water bottles, food coloring, oil and water.  Or add an alka seltzer tab for the fizzy effect.  Either way, be sure to give this one a try.

One more note-- after this science experiment, we stored the baby soda bottles on the light table. And, the fun lived on.  :)
